به شکل زیر بیان کنید که آیا موج نشان داده شده با چشم غیرمسلح قابل دیدن است یا خیر؟ چرا؟
Understand the Problem
سوال از ما میخواهد تا بررسی کنیم آیا موج نشان داده شده با چشم غیرمسلح قابل دیدن است یا خیر.
Answer
Not visible - wavelength is 300 nm, outside 400-700 nm.
The wave shown is not visible to the naked eye because its wavelength of 300 nm is outside the visible spectrum (400-700 nm).
Answer for screen readers
The wave shown is not visible to the naked eye because its wavelength of 300 nm is outside the visible spectrum (400-700 nm).
More Information
The range of wavelength visible to human eyes is between 400 to 700 nanometers. Wavelengths outside this range fall into ultraviolet or infrared spectrum, which aren't visible to humans without assistance.
Tips
A common mistake is to assume wavelengths close to the visible range might be visible; however, visibility is strictly within 400-700 nm.
